Abstract

A self fusing alloy thermal spray coating or a vitreous ceramic coating is fused to a complicated metal shape or convoluted metal surface, such as a waterwall panel having a plurality of tubes interconnected by a plurality of membranes, without significant warpage or adverse change in the microstructure of the material forming the panel. The coating can first be applied to the panel and can then be heated to a liquidus temperature (typically between about 1000 DEG C - 2200 DEG F), by induction at a frequency of greater than about 25 kHz, so as to effect fusing. An inductive coil assembly for this purpose comprises a copper tubular combined electrical current conductor and conduit for circulating cooling water having a first closed end and a second end connectable to a source of cooling fluid and a source of electricity. At least one, and preferably a plurality, of copper noses extend outwardly from the combined conductor and conduit and both conduct electricity and circulate cooling fluid. The noses extend substantially perpendicularly to the combined conductor and conduit and are configured so as to effect proper induction heating of the panel. A magnetic flux concentrator is preferably provided over at least some of the noses. Preheating noses (e.g. solid copper blocks) may be connected to a leading portion of the combined conductor and conduit.

Description

..... * ........... j 4 606 1 9 1 1 A7 B7 Γ ^ ΙΜ Explanation (M) This invention relies on the water wall pipe row, the coating is induced by high frequency induction Melting method. (In the past, melting and spraying the thermal spray bell layer on the water wall tube can be completed by various combustible gas (natural gas, ethylene block, acrylic, etc.), oxygen and welding torch devices. The liquidus temperature of the tube can be allowed to be “hard-welded”. Metallurgical bonds are formed on the water preparation surface. This process has many disadvantages. First, the membrane part of the transfer tube must be melted but not occur. Overheating, perforation, or smelting on the side wall is interrupted, or small tubes are arched; another problem is that when using a torch, a large amount of heat (BTUs) is needed to heat the water wall tube to make it high enough. The temperature of the layer can reach its liquid phase temperature. The high thermal conductivity and the thermal quality of the water wall * allow the heat to escape from the coating very quickly. Only the entire tube thickness of the water wall tube has been completely heated. The result shows that it is actually heated enough to cause the small tube to arch, but it is still not melted. This high heat loss will make the small tube and the tip material, and the potential for correction in the small ## Changes in the microstructure of the water, this change has a negative effect on the performance or use of the water wall Yes, try to use money, tube; MH, tube has been shown to pull the heat too fast, the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economy will print the system quickly because the welding moment provides too little heat to overcome the heat caused by the related Area escape. The third point is that the welding torch melting technology is extremely time consuming and difficult to control to achieve consistency. In the past, induction heating has been used for individual straight pipes and can be used as a molten thermal blasting layer. Induction heating is performed on complex shapes, such as on water wall pipes. Previous efforts have focused on relatively low frequency (less than rugged) induction heating applications. The results have been proven ^ This paper standard is applicable to China Standard (CNS) Λ4 specification (210x297 mm) --- & 21L2a 4 6〇s ig A7 B7 V.
